11 years agotracing, ring-buffer: add paranoid checks for loops
Steven Rostedt [Fri, 31 Oct 2008 13:58:35 +0000]
tracing, ring-buffer: add paranoid checks for loops

While writing a new tracer, I had a bug where I caused the ring-buffer
to recurse in a bad way. The bug was with the tracer I was writing
and not the ring-buffer itself. But it took a long time to find the
problem.

This patch adds paranoid checks into the ring-buffer infrastructure
that will catch bugs of this nature.

Note: I put the bug back in the tracer and this patch showed the error
      nicely and prevented the lockup.

11 years agoftrace: use kretprobe trampoline name to test in output
Steven Rostedt [Fri, 31 Oct 2008 19:44:07 +0000]
ftrace: use kretprobe trampoline name to test in output

Impact: ia64+tracing build fix

When a function is kprobed, the return address is set to the
kprobe_trampoline, or something similar. This caused the output
of the trace to look confusing when the parent seemed to be this
"kprobe_trampoline" function.

To fix this, Abhishek Sagar added a test of the instruction pointer
of the parent to see if it matched the kprobe_trampoline. If it
did, the output would print a "[unknown/kretprobe'd]" instead.

Unfortunately, not all archs do this the same way, and the trampoline
function may not be exported, which causes failures in builds.

This patch will compare the name instead of the pointer to see
if it matches. This prevents us from depending on a function from
being exported, and should work on all archs. The worst that can
happen is that an arch might use a different name and then we
go back to the confusing output. At least the arch will still build.

sparc64: Fix PCI resource mapping on sparc64

There is a problem discovered in recent versions of ATI Mach64 driver
in X.org on sparc64 architecture. In short, the driver fails to mmap
MMIO aperture (PCI resource #2).

I've found that kernel's __pci_mmap_make_offset() returns EINVAL. It
checks whether user attempts to mmap more than the resource length,
which is 0x1000 bytes in our case. But PAGE_SIZE on SPARC64 is 0x2000
and this is what actually is being mmaped. So __pci_mmap_make_offset()
failed for this PCI resource.

11 years agox86: Clean up late e820 resource allocation
Linus Torvalds [Sat, 1 Nov 2008 17:17:22 +0000]
x86: Clean up late e820 resource allocation

This makes the late e820 resources use 'insert_resource_expand_to_fit()'
instead of doing a 'reserve_region_with_split()', and also avoids
marking them as IORESOURCE_BUSY.

This results in us being perfectly happy to use pre-existing PCI
resources even if they were marked as being in a reserved region, while
still avoiding any _new_ allocations in the reserved regions.  It also
makes for a simpler and more accurate resource tree.

Example resource allocation from Jonathan Corbet, who has firmware that
has an e820 reserved entry that covered a big range (e0000000-fed003ff),
and that had various PCI resources in it set up by firmware.

With old kernels, the reserved range would force us to re-allocate all
pre-existing PCI resources, and his reserved range would end up looking
like this:

e0000000-fed003ff : reserved
  fec00000-fec00fff : IOAPIC 0
  fed00000-fed003ff : HPET 0

where only the pre-allocated special regions (IOAPIC and HPET) were kept
around.

With 2.6.28-rc2, which uses 'reserve_region_with_split()', Jonathan's
resource tree looked like this:

e0000000-fe7fffff : reserved
fe800000-fe8fffff : PCI Bus 0000:01
 fe800000-fe8fffff : reserved
fe900000-fe9d9aff : reserved
fe9d9b00-fe9d9bff : 0000:00:1f.3
 fe9d9b00-fe9d9bff : reserved
fe9d9c00-fe9d9fff : 0000:00:1a.7
 fe9d9c00-fe9d9fff : reserved
fe9da000-fe9dafff : 0000:00:03.3
 fe9da000-fe9dafff : reserved
fe9db000-fe9dbfff : 0000:00:19.0
 fe9db000-fe9dbfff : reserved
fe9dc000-fe9dffff : 0000:00:1b.0
 fe9dc000-fe9dffff : reserved
fe9e0000-fe9fffff : 0000:00:19.0
 fe9e0000-fe9fffff : reserved
fea00000-fea7ffff : 0000:00:02.0
 fea00000-fea7ffff : reserved
fea80000-feafffff : 0000:00:02.1
 fea80000-feafffff : reserved
feb00000-febfffff : 0000:00:02.0
 feb00000-febfffff : reserved
fec00000-fed003ff : reserved
 fec00000-fec00fff : IOAPIC 0
 fed00000-fed003ff : HPET 0

and because the reserved entry had been split and moved into the
individual resources, and because it used the IORESOURCE_BUSY flag, the
drivers that actually wanted to _use_ those resources couldn't actually
attach to them:

e1000e 0000:00:19.0: BAR 0: can't reserve mem region [0xfe9e0000-0xfe9fffff]
HDA Intel 0000:00:1b.0: BAR 0: can't reserve mem region [0xfe9dc000-0xfe9dffff]

with this patch, the resource tree instead becomes

e0000000-fed003ff : reserved
  fe800000-fe8fffff : PCI Bus 0000:01
  fe9d9b00-fe9d9bff : 0000:00:1f.3
  fe9d9c00-fe9d9fff : 0000:00:1a.7
    fe9d9c00-fe9d9fff : ehci_hcd
  fe9da000-fe9dafff : 0000:00:03.3
  fe9db000-fe9dbfff : 0000:00:19.0
    fe9db000-fe9dbfff : e1000e
  fe9dc000-fe9dffff : 0000:00:1b.0
    fe9dc000-fe9dffff : ICH HD audio
  fe9e0000-fe9fffff : 0000:00:19.0
    fe9e0000-fe9fffff : e1000e
  fea00000-fea7ffff : 0000:00:02.0
  fea80000-feafffff : 0000:00:02.1
  feb00000-febfffff : 0000:00:02.0
  fec00000-fec00fff : IOAPIC 0
  fed00000-fed003ff : HPET 0

ie the one reserved region now ends up surrounding all the PCI resources
that were allocated inside of it by firmware, and because it is not
marked BUSY, drivers have no problem attaching to the pre-allocated
resources.

it's still very wrong.

Switch the i915 device aperture mapping to the io-mapping interface, taking

Keith Packard [Fri, 31 Oct 2008 02:38:18 +0000]
resources: add io-mapping functions to dynamically map large device apertures

Impact: add new generic io_map_*() APIs

Graphics devices have large PCI apertures which would consume a significant
fraction of a 32-bit address space if mapped during driver initialization.
Using ioremap at runtime is impractical as it is too slow.

This new set of interfaces uses atomic mappings on 32-bit processors and a
large static mapping on 64-bit processors to provide reasonable 32-bit
performance and optimal 64-bit performance.

The current implementation sits atop the io_map_atomic fixmap-based
mechanism for 32-bit processors.

This includes some editorial suggestions from Randy Dunlap for

I noticed that, under certain conditions, ESRCH can be leaked from the
xfrm layer to user space through sys_connect. In particular, this seems
to happen reliably when the kernel fails to resolve a template either
because the AF_KEY receive buffer being used by racoon is full or
because the SA entry we are trying to use is in XFRM_STATE_EXPIRED
state.

However, since this could be a transient issue it could be argued that
EAGAIN would be more appropriate. Besides this error code is not even
documented in the man page for sys_connect (as of man-pages 3.07).
